Incroyables and merveilleuses
The Incroyables (French: [ɛ̃kʁwajabl], "incredibles") and their female counterparts, the Merveilleuses (French: [mɛʁvɛjøz], "marvelous women"), were members of a fashionable aristocratic subculture in Paris during the French Directory (1795–1799). Whether as catharsis or in a need to reconnect with other survivors of the Reign of Terror, they greeted the new regime with an outbreak of luxury, decadence, and even silliness.
